Kathleen "Kathy" Rusteberg, nee Hill, 80, of Waterloo, IL, died February 26, 2025, in Waterloo, IL. She was born August 19, 1944, in E. St. Louis, IL.

 She is survived by her beloved husband, Emmett Rusteberg, her children, David (Deborah) Rusteberg, Lori Santel and her husband Lance Brunkow, and Todd (Sony) Rusteberg; and her cherished grandchildren: Brennan, Blake, and Brianna Rusteberg; Logan, Landon, and Lily Santel, and Skylar and Shaylee Rusteberg. She is also survived by her great-grandchildren, Ansley and Vincent Santel, daughter and son of Logan and Sierra Santel. Additionally, she is survived by her sister Barbara (Babs) and her husband Raymond Heinen and her brother Dennis Hill.

 Kathy was preceded in death by her parents, Robert and Clara Hill; her brothers Robert (Bob) Hill, Jim Hill, Michael Hill, and Thomas Hill; and her sister Patricia Niemann.

 Kathy’s career began as a secretary and office manager at Goldman Sachs. She later worked alongside her husband, Emmett Rusteberg, as a floral designer at Rusteberg Florist and Landscaping. Dedicated to her family, she went on to support the family business, Grassman Lawncare, as its secretary and office manager.

 Kathy and Emmett met at a SS Peter and Paul High School basketball game, where it was love at first sight. They dated throughout high school and married on August 24, 1963, building a beautiful life together over 61 years. 

 A devoted wife, mother, and grandmother, Kathy’s love for her family was unwavering. She was always a source of support and encouragement, deeply involved in her children’s and grandchildren’s lives. She took great joy in sharing stories and pictures of her grandchildren with friends, family, and even strangers, always beaming with pride.

 In her younger years, Kathy had a passion for waterskiing, boating, and camping with her family. Later in life, she found happiness in visiting her children and grandchildren and traveling to the family’s lake home in Branson, MO, and attending SS Peter and Paul Catholic Church with her family. Known for her kindness, warm smile, and keen sense of humor, Kathy’s presence brightened the lives of everyone she met.
